Well, I am researching a lot of altcoins at this moment and I found several gems alts that are already giving huge ROI, but for the new coin, I am not sure! Because if you are able to get in the presale or public sale of the new coin, then you will make a huge gain, but if you buy from the exchange after listing then you can get rekt too! This week, Curve coin listed on exchanges, I checked the price, it was 45$, means huge money for the early buyers. But whoever buys at that price, they got rekt, because right now Curve is trading under 15$! But still, I am suggesting you some new coin as you will dyor! Skale, Ken, Bart, Mantra DAO, DIA coins are looking potential to me, have some research on them. Good Luck!
